Connecting up the ILDA Board
The connections on S4p are 100% compatible with previous models (V1.xx) with the only addition of a negative power supply
line.
Connections – refer to the images above & connection diagram at the end of the document
ILDA input
– 25-way sub d male (on underside of PCB S4p only)
ILDA Input(/Output)
– Header for connecting IDC 26 way lead to be used as ILDA output (un-buffered) on S4p (left) and as ILDA in/out on S4i (right)
Colour Blanking outputs
– Provides buffered colour outputs for R,G,B, signals (8 way connector for back compatibility to V1.xx)
Remote Interlock
– 9 pin sub d on S4p and 10 way box header on S4i
For connecting Emergency stop button plus optional Start Button and Bi-colour LED for laser status (see connection details next page.)
Key switch
- connection for security key switch. This can also be used to connect other interlock loops such as a housing interlock switch.
Wire N/O contacts in series with key switch to facilitate this.
Emission LED
– Any 2v LED can be used directly across these pins. The emission LED should not be a Bi-colour type and if used only one LED will light.
Scanner Out
- Buffered X & Y axis scanner signals. Full differential outputs plus ground (centre pin – not normally needed)
Shutter output
– N/O relay contacts for placing in series with the shutter and its power source.
Not for mains power
. See specifications for maximum power ratings.
Shutter Closed LED
– Lights to indicate the status of the solid state shutter only. Lit = Shutter closed & laser output disabled.
Mains relay N/O contacts
- Connect in line (series) with mains live feed to laser modules (includes an inrush current suppression device.)
Power
– +/-24V DC power input. The board must be supplied from an ‘always on’ source as it switches power to the laser modules following a start-up time
delay. We would recommend using the scanner power supply as long as it has enough ‘spare’ current capability to power the board.
Scanfail
- Not used at this time, for future upgrade. The connector must be left open, shorting the pins will cause the solid state shutter to close preventing laser output.
S4i Version only
Projector Status Bi-Led
– Status indicator LED shows condition of the laser projector
(fitted to PCB on S4p)
Out - interlock loop broken or e-stop tripped
Green – Interlock loops good and e-stop reset - laser ready for start
Flashing red/green every second – Laser start-up sequence initiated.
Red – Laser active and power applied to laser sources
Power LED
– ILDA board has power
(fitted to PCB on S4p)
If you do not need a start function (laser output is below class IV) then the start
button pins can be joined on the rear of the 9-pin remote connector, and as soon as
the interlocks are all made the time delay will begin.
Should wish to implement a simple E-stop at your control station then the 9-way
remote interlock connector can be fitted with a shorting link (see diagram under
section ‘service plug’).
This simplified e-stop is only suitable if using a single stop per projector, and uses
the ILDA interlock between pins 4 and 17. These connections can be ‘broken out’ at
your remote control station adjacent to the laser control hardware. In this instance it
is recommended that the E-stop and Laser hardware (such as Pangolin FB3) be
wired in series so that the interlock loop is broken and laser power will be cut in the
event of the hardware becoming disconnected. (See wiring suggestion above right)
